If memory serves me correctly, the Model 1.2 slotted below the 1.8. There may have been one model between them at some point, which could be what you have.
As you said, it's a shame you can't post photos here. But, can you describe the shape, please? The Model 2 was pyramidal, like the Model 4. The designs under the Model 2 were not pyramidal, but had a sloped baffle. I think the Model 2 had both more drivers and larger woofers than you described.
Also, beyond talking to Jeff Joseph, Richard Modaferri, who patented the Infinite Slope crossover used by both companies, is someone to ask. And, you may want to contact the man himself, as in John Sollecito Engineering (JSE). I think I remember reading he lives in CT.
